APPARATUS FOR PROTECTING SAFES AND VAULTS.

SPECIFICATION forming part of Letters Patent No.350,823, dated October12, 1886.

Application filed March 9, 1885.

To all whom it may concern.-

Be it known that I, JosEPH FLEOKINGER, a citizen of Prussia, (havingdeclared his intention to become a citizen of the United States,) and aresident of Allegheny city, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inElectrical Safe-Protectors, of which the following is a specification.

My invention relates to improvements in the employment of electricity toprotect safes used for the deposit of valuable property; and the objectsof my improvements are, first, to warn unauthorized persons that thesafe is electrically protected; and, second, to cause the sounding of analarm should an attempt be made to open the door of a cage inclosing asafe or other object. I attain these objects by mechanism, illustratedin the accompanyiug drawings, in whicl1- Figure 1 represents a frontview of a metallic cage provided with my improvements. Fig. 2 is adiagram of a door-bolt and a portion of its locking device combined withan electric battery, an alarm, a switch, and part of the cage adapted toinclose a safe.

Similar letters of reference indicate similar parts in both figures.

A designates a metallic cage, which may be of any suitable size andshape, and which is properly insulated. B is the door of this cage,provided with a rectilinear sliding bolt, d, which is retracted whenfree by a spring, S. This bolt, which is suitably guided, is providedwith rectangular arms (1, as shown in Fig. 2, the ends of which areadapted to enter notches j in rotative cylinders J when these cylindersare all turned by means of knobs J, so that the notches register exactlywith the ends of said arms d. The bolt d is also provided with a pin,70, adapted to be acted on by a key, K, for shooting the bolt. \Vhen thebolt is shot, the cylinders J are turned, so that the notches j do notregister with the ends of arms d, and the bolt is locked. On the up peredge of the bolt (1 is a pin, 6, against which .is held, by a spring, 8,the tail f of a switch,

6, which is pivoted at b to the loclccase and suitably insulated. Inclose relation to this segment-shaped switch is a post, h, which iselectrically connected by a wire, G, with the electro-magnet of asuitable bell-arm, H.

Within the cage or elsewhere is a galvanic Serial No. 158,271. (Nomodel.)

battery or other suitable generator of electricity, (indicated by theletter 0,) from which a Wire, F, is carried to a metallic plate, 9.Another wire, F, connects the other pole of the battery or electricalgenerator with the alarm H. Other wires, E N D,'connect the metalliccage A with said generator, as shown in Fig. 2.

By the above-described contrivance an unlocking movement of the bolt dwill cause the pin 6 to press against the tailf of the pivoted switchand shift the same, so as to cause its metallic plate 9 to contact withthe post h, and thereby establish a complete circuit through the alarmH, thereby sounding it.

When the cage-door is locked, the bars and wires composing the entirecage will be brought within the electric circuit by the arrangement ofwires, as described, so long as the source of electricity is in properworking condition.

It is obvious that the alarm mechanism and the generator of electricitymay be located outside of the cage A in any convenient place.

Having described my invention, I claim 1. The combination of the slidingbolt d, provided with arms d, the notched cylinders adapted to operateas described, a retracting spring for the bolt, a pin, it, thereon for akey, the pin 6, the spring-actuated switch, the plate 9, electricallyconnected to a generator, 0, the post h, its electrical connection withthe alarm, and the electrical connection of the latter with saidgenerator, all as described and shown.

2. The combiuation,with the insulated cage A and its swinging doorprovided with a sliding bolt having a retracting-spring and an arm, e,of the spring'actuated switch, the plate 9, electrically connect-ed to agenerator, (7, the post h, electrically connected with an alarm, theelectrical connection of the latter with the generator and theelectrical connec tions of said cage with the wire G, leading from posth to the alarm, and the wire leading from the alarm to the generator,and also with the wires D F, leading through the switchplate 9 to thisgenerator, all substantially as described.
